美國Brookhaven國家實驗室、愛爾蘭科克大學和奧地利Graz技術大學的科學家發(fā)現(xiàn),，植物中常見的一種細菌和某種住院患者機會性感染相關細菌之間存在極大的相似之處,?？茖W家稱這一發(fā)現(xiàn)對生物技術具有重要影響，因為這種植物細菌在一系列生物技術中被應用,。
Daniel van der Lelie及其同事對兩種Stenotrophomonas maltophilia細菌進行了對比,。Stenotrophomonas細菌具有多種功能，并且能適應不同的環(huán)境,。某些菌種能導致血液和肺部感染,，而另一些則能促進植物生長。研究人員鑒定出能使兩種細菌對諸多抗生素產生抗性的基因,。據(jù)van der Lelie稱,，這表明抗生素抗性是該類細菌核基因組的一部分，而并非醫(yī)院中那種細菌的特有性狀,。他警告說,，盡管Stenotrophomonas已經表現(xiàn)了一定的潛力，比如促進植物生長,、保護植物免受病原體侵襲以及生產蛋白藥物和酶等,，但在生物技術中需謹慎應用這種細菌,。（生物谷Bioon.com）

The genus Stenotrophomonas comprises at least eight species. These bacteria are found throughout the environment, particularly in close association with plants. Strains of the most predominant species, Stenotrophomonas maltophilia, have an extraordinary range of activities that include beneficial effects for plant growth and health, the breakdown of natural and man-made pollutants that are central to bioremediation and phytoremediation strategies and the production of biomolecules of economic value, as well as detrimental effects, such as multidrug resistance, in human pathogenic strains. Here, we discuss the versatility of the bacteria in the genus Stenotrophomonas and the insight that comparative genomic analysis of clinical and endophytic isolates of S. maltophilia has brought to our understanding of the adaptation of this genus to various niches.
